PLC程序无论控制的是一个设备或者是以一套系统，在程序编写之前都应该按照功能或者区域设计好整个PLC程序系统的结构，尤其是几个人共用一套PLC系统的时候，一般来说结构应包括以下部分：
1、公共组织程序区：OB1、OB35、OB81....等（STEP7）
2、设备功能程序区：一些现成的可以多次调用的程序块，如单向电机、双向电机、模拟量转换
3、公共程序区：通讯功能、模拟量采集、数字量采集
4、功能区：如液压站功能区、入炉辊道功能区、出炉辊道功能区
5、报警功能区：根据需要或者在各个功能区后面，或者单独独立出来
6、数据块区：根据功能，划分成有规律的数据区
一个良好的结构，可以使人很容易看明白整套程序，具备良好的可读性
